Application filed September 25, 1913.

To all whom it may concern: r Be it known that I,W1I.L1s M. DERBY, a citizen of the United States, and a resident of Buchanan, county of Westchester, and State of New York, have invented a new and following is a full, clear, and exact description.

My invention has'fo'r its a gas scrubber having a spiral member for directing the gas in a circular path so that .all the impurities-and moisture will be di.

rected outwardly to be deflected by flanges through openings in a'wall at the outer side of the spiral. 1

Another object of the invention is to provide meansfor directing gas downwardly and spraying it at spiral to cool and remove some of the impurities, the gas then being permitted to pass upwardly through the spiral.

. in the wall.

tion of the scrubber Still another object of theinvention is to provide an outer casing spaced from the said wall to form a passage way for the impurities and flected by the flanges through theopenings Still other objects of the invention will appear in the which the preferred form of the invention is disclosed.

In the drawings ters refer to similar whichv Figure-1 is a vertical sectional view of my gas scrubber, and 2 is a sectidnal view on the line 2-2 of Fig. 1.

similar reference characparts 1n the two views in Iy gas scrubber is devised for operation without any internal moving mechanism and it may therefore be manufactured and operated at comparatively little expense and in fact no power is required in the opera-. except that. which is required to supply the Water to the sprays at preferably 30 to 40pounds pressure, to which of course, essary power to force or draw the gas from the producer through the scrubber.

y referring to the drawings it will be seen that a tubular casing 5 is provided which is shown in a vertical position, this tubular casing 5 having a head or bottom 6 and a head or top 7, there being an opening 8.in this head or top 7, through which the gas may pass to the tubular mem- Specification of Letters Patent.

her 9 which is disposed within the tubular casing 5, the tubular member 9 being of considerably less diameter than the tubular casing 5 as will be seen by referring to the drawings. The bottom 10 of the tubular member 9 is spaced from the header bottom 6 of the tubular casing 5 and this bottom 10 of the tubularmember 9 is supported on the legs 11 which rest on the head or bottom 6 of the tubularcasing 5. Disposed around the tubular member 9.and within the tubular casing 5 there is a second tubular member 12 which is of slightly less diameter than the tubular easing 5. The bottom 13 of this tubular member 12 extends below the horizontal bular member 9, but the tubular member 13 does not extend upwardly as far as the hori- {)ontgl plane at the top of the tubular 1fiemer I In order to close the space 14 between the plane at the bottom 10 of the tu- 5 at the top of the tubular member 12, I" provide members 15 which extend across this space and preventthe upwar'd flow of fluid between the tubular member 12and the tubular casing 5. members 9 and 12 there is a deflector or spiral 16 for giving the gases, flowing up; wardly between the tubular members 9 and 12 a circular motion so:- that the gas which Between the tubular flows down in the tubular member 9 and which has been sprayed by the sprayer 17 to remove impurities, is given a rotary or circular motion by the said deflector or sprial 16 for the purpose of throwing the impurities and moisture outwardly by centrifugal force and against the tubular:mem-,

casing 5 from which they will flow with the water from the sprayer 17 to the drain opening 20, in the head or bottom 6.

As has been stated thegas from the producer enters the scrubber through the pipe 21, a water pipe 22 extending horizontally into this pipe and being connected by an elbow 23 with'a pipe 24 leading to the sprayer 17. The gas after passing downwardly in the tubular member 9 and up:

,\ wardly between the tubular members 9 and 12 flows out through a port 25 at the side of the tubular casing 5 above the members 1.5. g The tubular members 9 and 12 may be constructed in sections and be secured together as desired so that they may be readily handled. In the bottom of the tubular casing 5 adjacent the head or bottom -6 there is a man-hole 26. The bottom of the tubular member 13 is supported by the legs 27 which rest on the head or bottom 6 of the tubular casing 5. The tubular member 12 and the tubular casing 5 are held. spaced apart by the members 29. r Claims.
